Asfsoon as the 9o f rod is moved to its normal position the ciry cuit through the transmitter is restored In the arrangement shown in-Fi s. 4 and 5 the lampgbracket is employed in ieu of the pushbar to open and close the lam circuit. 95 Thisis eifected by providing the cy inder or .'head19" ofthe desk-telephone with alined uides 20 to be engaged by lateral oisets' 21,

On the in,- side of the cylinder is a spring-contact 23in normal'contact with posts 24 25, with the 'former of which connects the battery-Wire4 26. With the post 25 connects a Wire 27, 105- `leading to the transmitter. (Not shown) Adjacent tothe post 25 4is a post 28, With which connects a wire 29, (shown in dotted selecting mechanismand dial forms no art gagement with the post 28, thus closing the circuit end lighting the lamp. A reverse movement of the bracket opens the lempcircuit and closes the transmitter-circuit.

It would be obvious that the same movement of the bracket which closes the lampcircuit also brings the lam into proper position to illuminate effectue ly the station-selecting means, While the reverse movement Which opens the lamp-circuit carries the lamp into a position where it is not liable to be broken.

As shown in Fig. 1, the lamp is combined with a telephone equipped With a selecting device having a novel form of dial 32. The

of the present invention and is not,'there ore, described; but the dial is of peculiar advantage and will be included herein. 1 Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-

1. In a telephone lighting system, the combinationof a telephone instrument having a transmitter, a receiver, and a hook for the latter, a transmitter-circuit, including a resilient 'contact and a binding -post against which the resilient4 contact normally rests, a lam' -circuit having a terminal secured to a bin ing-post disposed adjacent to that of the transmitter-circuit, a source of electrical energy for the circuits, and a slidable device l mounted in the instrument and'connected to and means for iiexing the contacts to cause them to engage the binding-posts of the lamp-circuit, thus to open the transmittercircuit and close the lamp-circuit.

3. In a telephone lighting system, a transmitter-circuit including resilient contacts and binding-posts with which the contacts normall engage, a le nip-circuit having its terminas secured to binding-posts disposed adjacent to those of the transmitter-circuit, a source of electrical energy for the circuits and a push-bar for actuating the contacts to open the transmitter-circuit and close the lamp-circuit. l

In testimony whereof we affix our signa'- tures 1n presence of two witnesses.
